Using the relatively new concept of a pullback attractor, we present some results on the existence of attractors for differential equations with variable delay. We give a variety of examples to which our result applies.

Consider the delay differential equation xЈ t q p t x t y s 0, where p t g Žw . q . C t ,ϱ , R and is a positive constant. We obtain a sharp sufficient condition 0 for the oscillation of this equation, which improves previously known results.
